A tiny hairline crack on cylinder 1, 2, and 3 between values. Head pressure checks OK. Guy at head shop say don't use cause at temperature cracks could get worse and/or leak. Any advice?

No way I'd use that thing. Call http://www.engnbldr.com, get a new one.

I reused mine and it held up fine until I sold the rig. Unknown where it's at now though.

I say try to get some good head.

just keep your eyes open. Used heads can be found for nearly nothing.

Buy a head

If you want to be sure the head you install has no cracks, there's a product for that. I used it in mechanics school and can attest that it's great.

when your finished with the procedure, the surface is like purple and any crack is white. It makes them really obvious. I searched on google and found it: http://www.carbuyingtools.com/tools_supplies/products/Magna_Flux_Crack_Detection_Kit_SK-416.asp
